d89882da16 Some more polish to make xargs act like GNU xargs (thanks to kent robotti 
<robotti@metconnect.com> for testing and pointing out the differences)

e081eae7a4 Final (I think) version of xargs. Throw away all that tedious string 
scrubbing, and quit using system.  Instead, use fork() and exec(), which
yields and smaller, simpler, and cleaner design.

Glenn L McGrath
63dde9d4ce Simplify and remove dependence on PATH_MAX 
buf[PATH_MAX] now defined using strlen to the exact size to be used.
removed output that was displayed if which didnt find the command, this makes itmatch the behaviour of GNU's which.
These modifications result in a slight size decrease.

322ae93a5e Fix calls to {m,c,re}alloc so that they use x{m,c,re}alloc instead of 
segfaulting or handling errors the same way themselves.

2ef880b236 Consolodated some common code into print_matched_line to make 'grep_file' a 
little more terse & clean. Also made a few minor formatting changes.

8f122431f5 Added support for the -c (count matches) option. Made it so it works just like 
GNU grep.

3bd8bd89ee Don't use strings directly in calls to usage(). This is in preparation 
for their extraction to a separate file.

c41e8c840f Changed bb_regcomp to xregcomp and #if 0'ed out destroy_cmd_strs in sed.c 
(maybe I'll remove it later).

df5f6ba115 Applied patch from Matt Kraai which does the following: 
- adds case-insensitive matching in sed s/// epxressions
 - consolodates common regcomp code in grep & sed into bb_regcomp and put in
   utility.c
 - cleans up a bunch of cruft

44735f8744 Applied patch from Matt Kraai as per his email: 
However, the case of

	grep foo$ file

didn't work, due to a problem with the flags used in regular expression
compilation.  The attached patch fixes this problem.

1ca41775bb Yanked out the cstring_alloc() and cstring_lineFromFile() functions from 
utility.c and replaced them with get_line_from_file() from the new grep.c.
Also changed declaration in internal.h and replaced instances of
cstring_lineFromFile() in dc.c and sort.c with get_line_from_file(). Tested
them and they worked fine.

d37218941c Brand, spankin', new grep that uses libc regex routines instead of the 
hand-rolled ones. Sed still needs to be replaced and then the regexp stuff can
be axed.

053b1462b7 Fix a bug pointed out by Michal Jaegermann <michal@ellpspace.math.ualberta.ca> 
where you used to see:
      ./grep -q -i B some_file
      B: No such file or directory
This is now fixed.

  Line is too long, anymore

up to 17k.
